Abstract

It was an object of the invention to provide, by use of new materials and membranes and with very little outlay, an inexpensive and long-lived redox flow cell which even in the event of a possible serious accident brings about little environmental pollution by its redox-active compounds.According to the invention, high molecular weight compounds such as redox-active polymers or oligomers are provided as redox-active components and a size-exclusion membrane (3) is provided as membrane for the separation of the high molecular weight redox-active components.
